"Use of the Marcrist Diamond Floor Shaver for decontamination of radioactive contamination from concrete floors has begun at Rancho Seco. The Marcrist Shaver was originally selected due to it's proven ability to remove between 1/8" to 1/4" of the contaminated concrete surface per pass at a production rate of approximately 100 ft2/hour; ease of operation as the shaver is self-propelled and can be operated and easily moved by a single worker, and generates a very dense waste product which results in a low volume of produced waste. However, most importantly, the Shaver leaves a smooth surface that is acceptable for final site radiological surveys. The resulting smooth surface helps to ensure that surface beta scans and direct measurements, supporting final site survey, are performed efficiently, effectively and reliably."

The Marcrist concrete shaver is the robust tool of choice for decontaminating concrete on large as well as small projects.  The Marcrist concrete shaving systems reduce floor, wall, and ceiling surface decontamination, including embedded metal, to an easy and predictable task.  High production precision shaving resulting in effective waste minimization and ease of surveying offer the benefit of cost and time savings while minimizing worker exposure.

User friendly and requiring minimal training our walk behind, self propelled floor shaver is a heavy duty performer.  Ganged diamond blades teamed with waste collecting HEPA vacuums eliminate the spread of contamination while making precision shaving passes 1/16 to 1/4 inches deep and 10 inches wide.  The resulting surface is a light corduroy, dust-free, concrete which can be easily surveyed and used as a finished surface.

The wall shaver is a ganged diamond blade cutting head, electric over hydraulic that is rail mounted, deployed by robotic arm or attached to the wall by vacuum pads or custom designed connections.  Shaving up to a 1/4 inch deep in a single pass, 11 3/4 inches wide, the wall shaver offers a safe, controlled best practice solution, to meet the demands of wall and ceiling decontamination.  

Used extensively at commercial operating sites, DOD/DOE operating, as well as decommissioning sites, the Marcrist shaver has established a track record of high production reliable performance.
